Title: Magnetic resonance imaging methods and apparatus
IPC: G01R33/565
Filed: 1989-01-30
Abstract: An incomplete set of three dimensinal magnetic 
resonance data (F(k₁, k₂, k₃) is collected and stored in 
acquired data memory (60). The incomplete data set is 
complete with respect to first and second directions and 
incomplete with respect to a third direction. However, the 
acquired data set has data along the third direction between 
±n central values and half the remaining values. One 
dimensional inverse Fourier transforms (64, 66) are 
performed with respect to the first and second directions to 
create an intermediate data set (68). A phase correction 
array or plurality of phase correction vectors p( r ) are 
generated from the intermediate data and stored in a phase 
correction memory (82). A symmetric data set (100) is 
created as the complex conjugate of the intermediate data 
set. The intermediate and symmetric data sets are one 
dimensionally inverse Fourier transformed (92, 104) with 
respect to the third direction one vector at a time to 
produce vectors of first and second complex image arrays 
(f A , F S ) corrected (96, 108) with the corresponding phase 
correction vector, and combined (110) into a line of a 
resultant three dimensional image representation (112).

Filed: 1989-05-25
Abstract: Apparatus (10) for machining a human 
tooth includes a rotary cutter (22) that is moved 
along a predetermined path dictated by 
motor energizing signals. The cutter is 
moved vertically by one drive, laterally 
by another drive and in or out by a third 
drive. The apparatus is clamped selectively 
to the patient's jaw or to a model 
thereof. The dentist's manual work is 
actually done on a model, with the apparatus 
being secured to the model in a fixed 
position. The vertical drive, the lateral drive, 
and the in or out drive are energized in 
response to the dentist's manipulation of a 
joy stick to move the cutter along paths 
necessary to achieve the desired tooth 
configuration. A second joy stick is 
manipulated to vary the attitude of the cutter, 
about roll and/or pitch axes. Signals 
proportionate to the extent of each drive 
operator are delivered to a computer in 
the sequence and for the period during 
which the drives are activated. When the 
machining is completed on the model, 
the restoration is prepared from the model, 
and the patient is then called back. 
The device is then secured to the patient's 
jaw so that it is in precisely the same 
relative position as on the model. Then, 
the computer delivers signals to the 
appropriate drive motors (M1, M2, M3) to repeat the 
appropriate machine strokes in the proper 
sequence to duplicate the machining previously 
done on the model.

Title: Receiver-combination for force, elongation and sound conducted through solids
IPC: G01L5/16
Filed: 1991-05-21
Abstract: In the process monitoring of CNC-controlled processing machines, the installation of uni- and multi-axial force measuring sensors and of strain measuring sensors has already been setting the trend. New possibilities can be opened up by structure-borne sound sensors. According to the invention, a new pick-up category is created by combining force and structure-borne sound sensors and strain and structure-borne sound sensors. The effect of combining these basic sensor technologies provides synergy effects covering a wider band of process monitoring and brings greater reliability into structure-borne sound evaluation analysis. In addition, the effect of the combination enables the sensor technology to be accommodated close to the process at the point of origin of the parts emitting the force and structure-borne sound. The proposed novel combined pickups thus create sensor elements for wide-range process and plant monitoring.
